The adjustable clock program through the serial data 1. Program Description: This example demonstrates how to set the clock via the serial data, the use of digital display. 2: 1, 1 serial port that can be set to output via USB port or via DB9 port output. If you use a USB output, use a USB cable connected to the computer board, If you use a DB9 output, use a DB9 straight cable to connect the socket J25 development board to the computer. While the socket J28 jumper to jump TxD1 and RxD1. Open the STC-ISP download software serial assistant, the corresponding serial number, Select the baud rate of 9600, 8 data bits, 1 stop bit, no parity. Point to open the serial port receive buffer HEX mode Transmit Buffer Select HEX mode Input data serial format to send aides area below aa 55 n1 n2 n3 n4 n5 n6 n7 xx Wherein aa 55 to start two data, xx To verify that data, n1 n2 n3 n4 n5 n6 n7 seconds, minutes, hours, day, date, month, and year of data.
